SANDPAPER HOLDER Filed May 29. 1930 jgard ofefl'an Patented May 17, 1932 UNITED STATES PATENT ol-ricizI f RICHARD MONTBRIAND, F MILWAUKEE, WISCONSIN, ASSIGNOR TO PAUIP A. ZLOMKE,

0F MILWAUKEE, WISCONSIN SANDPAPER Homann Application filed May 29,

This invention relates to improvements in sandpaper holders.

One of the objects of my invention is the provision of an improved type of holder whereby strips of sandpaper can be applied thereto and the major portion of the sandpaper will be tightly fitted to a comparatively smooth stationary surface and will be retained in intimate contact with this surface while the sandpaper is being used as an abrasive instrument and includes means whereby the holder can be manually operated.

Another object of this invention is the provision of a. sandpaper holder which includes pivotally connected sections having improved means for clamping the ends of a strip of sandpaper to the upper surface of these sections with a major portion of the sandpaper strip retained in intimate contact with the other face of the sec-tions and also provides means for retaining the abutting` ends of the sections in intimate contact endfor-end, so that the surface over which the major portion of the sandpaper strip is eX- tended will provide a comparatively even surface.

A further object of the invention is the provision of an improved sandpaper holder wherein strips of sandpaper can be quickly and easily applied thereto, or detached therefrom and includes a suitable hand grip attached to one face of the supporting block so that the holder can be readily manipulated by hand.

With the above and other objects in view, the invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawings wherein:

Figure 1 is a perspective view of an improved sandpaper holder constructed in accordance with this invention ;V and,

Figure 2 is a longitudinal sectional view with the sections of the holder in supported position.

Referring more particularly to the drawings, it will be noted that the block to which the sandpaper is attached, comprise the sections 1 and 2 having their opposed ends bevf plate 7.

pivotally connected topsection 1 by means of pins 6, whereby the two sections 1 and 2 are pivotally connected for swinging movement in one direction, but the bevel face Vat theinner ends of the sections will prevent swing'- ing movement inthe other direction.

Pivotally connected to each section adjacent the outer end thereof is a retaining Each plate 7 is provided with spaced ears 8 adapted to be disposed upon opposite sides of each section and pivotally connected thereto by means of the screw members 9. Each retaining or clamping plate 7 is provided with a longitudinal-slot 10 through which the ends of the sandpaper strip is extended, as more clearly illustrated in Figure 2, and each retaining or clamping plate has struck from the body portion thereof, at one side of the slot 10, the penetrating prongs 11 which are adapted to penetrate the ends of the sandpaper strip,as shown in Figure 2, and when the clamping plates are moved down toward the upper face of the sections 1 and 2, these prongs 11 penetrate the ends of the sandpaper strip 12 and engage within recesses-13 in the upper faces of the sections 1 and 2. Furthermore, when the clamping plates are moved to operative position, as shown at the outer end of sections 2, in Figure 2, the strip has a tendency to be crimped through its position relative to the clamping plate and this, in addition to the prongs 11, will securely retainthe sandpaper strip tightly against the lower face of the sections 1 and 2, as shown in Figure 1, when the sections are moved to' aligning position.l

Attached to the upper face of section 1 is-a hand grip 13', and at one end of the hand grip, there is provided a retaining pin 14 adapted to engage within an opening 15 in the yieldable plate 16. vThe plate 16 has its lowerv end laterally disposed, as shown at 17, and securely attached to the upper face of section 2, by means of screw member 18.

The outer end of plate 16 is curved outwardly, as shown at 19, so that when the two sections are movedto aligning positions, one end of 'the hand grip 13 will engage this curved portion and urge the plate 16 outwardly until the hand grip has moved to its operative position -in contact with the headof the screw 18. It will be noted that in order to accommodate the head of the screw 18, one end of the hand grip 13 is cut away "asshown at 20, and when the hand grip is in position, as shown in Figure 1, the plate 16 will lit snugly against the end thereof, whereby pin 14 willenter opening 15 and retain sections 1 and 2 in aligning position.

-It lwill be apparent from the foregoing that I have provided va simple and inexpensive holder Yfor retaining strips of sandpaper `in a tight position against one face of a block, `so that the sand paper can be used as an abrasi ve-tool, and when the usefulness ofthe sandpaper strip has been expended, the strip can be easily removed and replaced with a new strip. By providing the clamping plates 7 with the slots 10 and passing the ends of vthe strips through the slots and `then :engaging these ends with the penetrating prongs 11, the strip will be securely held in a comparatively :tight position, so that the major portion of thestrip will be retained in intimate contact withone face ot the sections 1 and 2 when thesesections are disposed in longitudinalalignment, as shown in Figure 1, and will reduce Vtoa minimum zthe chanceof the ends of the strip `from turning vfrom beneath vthe clamping eplates.

The deviceas-descrihed and illustrated isof a `-veryrsimpleiconstruction and due to the use ofa minimum amount of parts, it is believed that the-same canibemanufactured and placed on the market at a very low cost.

While I have shown and described the preferred embodiment of my invention, it will beapparentthat slight changes may be made in the construction when putting the invention into practice wit-hout 'departing from the spirit of the same or the scope of the appen ded claim.

I claim: A

In a sand paper holder, a body having its upper faceprovided with recesses, a sand paper retaining plate hingedly carried by the body and overlying the upper top ace of the body :and extending transversely across the same, the plate havingasandpaper receiving slot therein extending substantially the full length of the same, and depending prongs carried by `the inner face of the plate for extension through said paper threaded through the'slot'and into the recesses in the body, when the plate is in its lower vposition and in engagement with the top face of the body.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin. l
